This webpage presents data on COVID-19 cases with information on pregnancy status reported to CDC.
COVID-19 is a nationally notifiable disease, a disease that the law requires be reported to public health departments and agencies.
Reporting cases to CDC is supported by routine case notification through the National Notifiable Diseases Surveillance System (NNDSS), as well as resources provided through the CDC COVID-19 response.
As of March 2022, CDC no longer recommends universal case investigation and contact tracing and recommends that health department jurisdictions prioritize specific settings and groups at increased risk. In addition,
a decreasing number of case reports include information on pregnancy status, and those that do may also have other information missing.
CDC will end reporting of these data in summer 2022.
CDC continues to support other efforts to learn more about the impact of COVID-19 during pregnancy.
From May 31, 2022 forward, data on this page will be updated on a quarterly basis. The National Blood Donor Seroprevalence Survey concluded monthly data collection in December 2021. This study is being modified and estimates will cover 3-month periods. CDC currently plans to end nationwide seroprevalence studies in December 2022.
